Sir Alex Ferguson revealed last night that the Glazers have never stopped him buying a player.

And in a robust defence of the despised American family - hated by most United fans for saddling the club with crippling debt after their £790million takeover in 2005 - the Old Trafford boss insisted their ownership has not hurt his team.

United still have debts of £423m and are paying massive interest charges which wipes out the huge yearly profits generated by the global commercial popularity of the club.

But Ferguson believes they've been good to him and United.

"So if you're asking me for my views, I don't have any complaints. I have never encountered opposition," he says.

"They've always been as sensible as they can be in terms of financing the team and they have to invest in the team to maintain the value of their asset.

"I think the problem for them is they are not publicists. They don't go out of their way to seek good publicity. They are quite happy to stay in the background and Abramovich is the same at Chelsea."

The Red Devils boss insists the family are investing in the future of the club.

"Just look at what they are spending on the training ground," he added. "It's going to be marvellous with a new sports science and medical centre, outdoor astro-turf pitches, a new viewing gallery and a groundsmen's work base.

"At the moment it's a bit of a bomb site but it will hopefully be completed by October and they will have spent about £30m on it, which is fantastic.

"United are different to other clubs in that there are a whole lot of factions who think they own the club.

"And for all the good intentions they show there will always be contentious issues around whoever owns the club.

"When I came to the club Martin Edwards was always getting pelted because he was going to sell to Maxwell, then to Murdoch, then Michael Knighton.

"When we were a PLC, there was disaffection and when the Glazers came in more disaffection."
